Exercise 04-9 Using departmental overhead rates to assess prices LO P2 Way Cool produces two different models of air conditioners. The company produces the mechanical systems in its components department. The mechanical systems are combined with the housing assembly in its finishing department. The activities, costs, and drivers associated with these two manufacturing processes and the production support process follow. Process Activity Components Changeover Machining Setups Driver Number of batches Machine hours Number of setups Quantity 800 6,000 120 Finishing Welding Inspecting Rework Overhead Cost $ 500,000 279,000 225,000 $1,004,000 $ 180,300 210,000 75,000 $ 465,300 $ 135,000 32,000 65,000 $ 232,000 Welding hours Number of inspections Rework orders 3,000 700 300 Support Purchasing Providing space Providing utilities Purchase orders Number of units Number of units 450 5,000 5,000 Additional production information concerning its two product lines follows.

Determine departmental overhead rates and compute the overhead cost per unit for each product line. Base your overhead assignment for the components department on machine hours. Use welding hours to assign overhead costs to the finishing department. Assign costs to the support department based on number of purchase orders. 2. Determine the total cost per unit for each product line if the direct labor and direct materials costs per unit are $250 for Model 145 and $180 for Model 212. 3. If the market price for Model 145 is $820 and the market price for Model 212 is $480, determine the profit or loss per unit for each model
